Luminous Broodmoth + Pitiless Plunderer + Slimefoot and Squee + Yahenni, Undying Partisan

Luminous Broodmoth

Pitiless Plunderer

Slimefoot and Squee

Yahenni, Undying Partisan

How it works

1. Activate Yahenni by sacrificing Slimefoot and Squee.
2. When Slimefoot and Squee dies, Luminous Broodmoth and Pitiless Plunderer trigger.
3. Resolve the Luminous Broodmoth trigger, returning Slimefoot and Squee from your graveyard to the battlefield with a flying counter on it.
4. When Slimefoot and Squee enters, it triggers, creating a 1/1 Saproling creature token.
5. Resolve the Pitiless Plunderer trigger, creating a Treasure token.
6. Activate Yahenni twice by sacrificing Luminous Broodmoth and Slimefoot and Squee.
7. When Slimefoot and Squee and Luminous Broodmoth die, Pitiless Plunderer triggers twice, creating two Treasure tokens.
8. Resolve the Yahenni abilities from steps 1 and 6.
9. Activate the Treasures by tapping and sacrificing them, adding .
10. Activate Slimefoot and Squee by paying 1 and sacrificing a Saproling.
11. When the Saproling dies, Pitiless Plunderer triggers, creating a Treasure token.
12. Resolve the Slimefoot and Squee ability, returning it and Luminous Broodmoth from your graveyard to the battlefield.
13. When Slimefoot and Squee enters, it triggers, creating a 1/1 Saproling creature token.
14. Activate a Treasure by tapping and sacrificing it, adding 1.
15. Repeat.

This clever loop turns the cycle of life and death into an engine using Luminous Broodmoth to constantly rescue fallen heroes by trading their lack of wings for a flying counter. Pitiless Plunderer quietly watches the carnage unfold, turning every single creature's demise into a shiny Treasure to help fund your spells and abilities. Meanwhile, Slimefoot and Squee acts as both the engine's recurring heart—bringing back itself and its allies while dropping fresh Saprolings into play—and Yahenni, Undying Partisan steps up as the willing executioner, using its sacrifice outlet to keep the whole process looping indefinitely.
